A ridge of high pressure along the east coast is also feeding moisture laden easterlies into these troughs. The combination of heat, moisture, and instability can cause isolated to scattered thunderstorms to develop over the northeast, central, and southeast parts of the state from this weekend onward. Some thunderstorms may be severe, with lightning, large hail, and wind gusts.
